Natural gas desulfurization and hydrogen production technology

Natural gas desulfurization and hydrogen production technology Based on the original synthetic ammonia gas making process, Liaohe Oilfield has boldly reformed the reformer, desulfurization transformation and heat recovery system, adopted innovative devices, greatly reduced compared with the old process, and reduced the natural gas consumption by about 1 / 3. Technical features: after pressurized desulfurization, natural gas is cracked and reformed with steam in a special reformer filled with catalyst to generate conversion gas of hydrogen, carbon dioxide and carbon monoxide. After recovering part of the heat, the CO content in the conversion gas is reduced by conversion, and the conversion gas is purified by pressure swing adsorption (PSA). Main performance indicators. Under a certain pressure, a composite adsorption bed composed of activated carbon, silica gel, molecular sieve and alumina adsorbents is used to adsorb the impurity components in various hydrogen containing gas sources such as methanol pyrolysis gas, synthetic ammonia purge gas, catalytic cracking dry gas, shift gas, water gas and semi water gas in refineries under low pressure, and the hydrogen difficult to adsorb is output as product gas from the outlet of the adsorption tower, To purify hydrogen. Production capacity: generally 400 ~ 20000 Nm3 / h according to user needs; Product purity: 99% ~ 99.999% (V / V); Product pressure: 1.3 ~ 2.0mpa-g; Main technical indicators. Raw material handling capacity: 10 ~ 5000NM / h; Adsorption pressure: 0.8MPa ~ 2.4Mpa; Hydrogen purity: 99.9 ~ 99.99%; Hydrogen extraction rate: 75 ~ 90% (depending on feed gas conditions and product gas requirements)
